From 4463aee630685a6ac595b1acc777536f0a41d02d Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Wed, 21 Sep 2011 20:49:29 +0200 Subject: pc: Unbreak ROM mapping for ISA machine MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is based on the original fix by Hervé Poussineau: pc_memory_init actually takes a memory region for mapping BIOS and extension ROMs. That equals the PCI memory region if PCI is available, but must be system memory in the ISA case.
